| H A D | sys_pipe.c | diff 91968 Sat Mar 09 20:06:31 MST 2002 alfred Don't deref NULL mutex pointer when pipeclose()'ing a pipe that is not fully instaniated. Revert the logic in pipeclose so that we don't have the entire function pretty much under a single if() statement, instead invert the test and just return if it fails. Submitted (in different form) by: bde Don't use pool mutexes for pipes. We can not use pool mutexes because we will need to grab the select lock while holding a pipe lock which is not allowed because you may not aquire additional mutexes when holding a pool mutex. Instead malloc(9) space for the mutex that is shared between the pipes. |
